Question

Find the value of x. PLEASE HELP!!!!!

I need to show my work.

Answer 1

x-60

Explanation:

Well the expressions lie on a straight line so I know that both of the added together will equal 180.

So the equation looks like this-(x-1+2x+1=180)

So when I substitute 60 in the equation it looks like this-(60-1+2(60)+1=180)

To solve-60-1+120+1::59+120+1::60+120

180
